To all whmn it 122 ag concern:

Be it known that we, CHARLES E. VHI'IE and CHAnLEs H. MCINTOSH, citizens of the -United States, and residing in the city and county of San Francisco,State of California, and at Berkeley, count of Alameda, State of California, respectively, have. invented a new and useful Improvement in Internal-Combustion Pumps, of which the following is a specification.

Our invention relates tov internal com-' v bust-ion pumps wherein liquid is elevated by 'means of the expansive force of an exploded gas that has previously been compressed in the combustion chamber by the pressure of a liquid piston within the delivery pipe of the said pump and its objects are, first, to provide improved means whereby the pressure of the liquid being discharged will compress gas into a receiver adjacent to the combustion chamber, second, to provide means whereby the full static pressure of the liquid within the delivery pipe will exhaust the burned gases from the combustion chamber, close the exhaust valve and permit the compressed gas within the receiver to enter the combustion chamber, third, automatic means for igniting the compressed gas within the combustion chamber, and fourth, to provide automatic means for drawing an explosive gas into the compression chamber previously to the compression of the said gas into the receiver. We accomplish these several features by means of the device illustrated in the accompanying drawings in Which Figure 1 is a broken sectional view of the.

device disclosing the inlet valve open and a charge of explosive gas entering the combustion chamber. Fig. 2 is a vertical sectional View, partly broken, showing the manner in which the expansion due to the exploded gas in the combustion chamber bustion chamber secured to the upper end of the pipe 2. A delivery pipe consisting of a return joint 3 and the pipe. 5, is in'turn secured to the lower end ofthe pipe 2 and is provided with an intake valve 4 which is held to its seat by improved means of the spring 4 secured to the stem thereof. The pipe 5 is secured to the end of the return joint 3 and is provided at its upper end with the member 6 havinga lateral discharge and the compression chamber 7 wherein a piston 8 is adapted to reciprocate vertically.

A gas supply pipe 9, having a check valve 9, communicates with the compression chamber 7 for the purpose of supplying gas thereto. A pipe 10, having a check valve 10', provides communication between the compression chamber 7 and the receiver 11 wherein the compressed gases are confined before liberation into he combustion cham. her 1. The pipe 12 is used to connect the receiver 11.. with the inlet port 14 controlled by the inlet valve 15 on the stem 16, said stem '16 being adapted to operate the arm 17 of the magneto 17 in a manner hereinafter more fully described.

An exhaust valve 18 controls the exhaust port 19. The stem 20 oft-he valve 18 is secured by means of the yoke 21 to a stem 22 secured to a piston 23 operating within the cylinder 24. The upper end of the stem 22 is provided with alatch 25 which is adapted to pass on its downward and engage on its upward movement, the pivoted lever 26 which looks the securing arm 27. The securing arm 27 isadapted to engage a col lar 28 secured to the upper end of the stem 16, of the inlet valve 15, and to hold the said valve closed against the pressure of the compressed gas within the receiver 11. 30 is a spring for closing the valve 15.

A connecting pipe 31 provides communication between the port 32 in the combustion chamber 1 and the cylinder 24. The combustion chamber is provided with the spark plug A for the purpose of igniting the gas in the said chamber.

The operation is as follows: The device being immersed in the liquid to be elevated and a quantity of water being in the combustion chamber 1, a charge of compressed gas is admitted to the said chamber 1 through the open inlet valve 15 until the pressure of the said charge within the said chamber l'is equivalent to the pressure within the receiver 11, when the stem 16 of the said valve is elevated by means of the spring 30 which closes the inlet valve 15, and, the latch 29. secured to the collar 28 on the upper end of the said stem 16, engages and elevates the lever 17 of the magneto 17 until said latch 29 passes beyond the range of the said lever 17 and releases the same. The release of the lever 17 produces a spark on the spark plug A and fires the charge of gas within the combustion chamber 1. The expansive force due to the explosion of the gas within the chamber 1 forces the liquid in the delivery pipe 5 upwardly against the piston 8 within the compression chamber 7 and compresses the gas therein through the pipe 10 and check valve 10 and into the receiver 11. The continued flow of the liquid in the delivery pipe 5 draws-an additional supply of liquid through the intake valve 1 by suction and forces the same through the delivery spout 6, Fig. 2. of the drawings. After the expansive force of the exploded gas in the chamber 1 is spent the exhaust valve 18 drops bvgravity an dopens the exhaust-port 19. The pressure of the returning liquid within the delivery pipe 5 forces the burned gases through the exhaust port 19 and permits the piston 8 within the compression chamber 7' to fall by gravity and automatically draw anew charge of gas through the supply pipe 10, and the valve 10, into the compression chamber 7. When the level of the liquid reaches exhaust valve 18 it closes the same and also exerts a pressure through the port 32, pipe 31 and into the cylinder 24 against the under face of the piston 23 which pressure assists in 010s ing the said xhaust valve 18 inasmuch as the stem 20 of the valve 18 and the stem 22 of the piston 23, are connected as at 21. The closing of the said valve 18 elevates the stem 20 thereof and causes the pivoted latch 25, secured to the upper end of the said stem 20, to engage the lever 26 and release the lever 27 which in turn allows the stem 16 of the inlet valve 15 to drop and open the said valve. The pressure of the compressed gas within the receiver 11, being greater than the pressure within the combustion chamber 1 and the tension of the spring 30, opens the inlet valve 15 and forces the gas into the said combustion chamber 1 where it is further compressed by the combined static pressure and the momentum of the returning liquid within thedelivery pipe 5 ready for the next explosion. As soon as the pressure of the gas within the combustion chamber 1 and the. inlet port 14 is equalized the tension of the spring 30 closes the valve 15 and tires the charge within the said chamber 1 as hereinbefore described.

- It is obvious from the foregoing that we have provided a device wherein the expansive force of an exploded gas within thecoinconnected thereto and having bustion chamber 1 discharges the liquid from the delivery pipe and thereby draws liquid through the intake valve 4 by suction, at the same time compressing the gas for the subsequent charge. Also the pressure of the returning liquid within thedelivery pipe 5 exhausts the burned gases and compresses the new charge within the combustion chamber. It is also evident that the piston 8 is adapted to automatically draw a new charge of gas into the compression chamber after each discharge of the liquid. We have also provided means whereby the closing of the exhaust valve automatically releases the inlet valve and the closing of the said inlet valve automatically fires the charge within the combustion chamber.

' The details of construction being so susceptible to variation. we do not wish to confine ourselves to the precise construction shown herein but rather to avail ourselves of any modification. that may fall properly within the scope of our invention.
